expanding upwards and in the representation of the upper 

 parts of the stalk in imitation of Dictyophora. 



Watson's unpublished figure shows a specimen 15 cms. high. 

 The volva is brown, with darker brown patches. The head 

 is 2 cm. high, broader than the stalk, but the openings below 

 it are only about 2 mm. long. The specimen had six arms, 

 and these (in error ?) are represented as free, though in 

 contact, at the rounded apex : at least this deduction appears 

 to be warranted by the fact that six black lines meet at the 

 apex. These black lines represent the spaces between the 

 arms, and it is possible that the artist has carried them 

 too far, or that the junction of the median furrows was 

 obscured. 



Another unpublished figure, drawn by W. de Alwis under the 

 direction of Dr. Thwaites, shows a specimen 14 cm. high. The 

 volva is white, with brownish yellow stains. The stalk thick- 

 ens somewhat abruptly towards the apex , but it was evidently 

 damaged in this part. Numerous perforations are figured 

 all over the stalk. The head, which is 2 cms. high, is at 

 first of the same diameter as the stalk, and tapers gradually 

 to the top, and the gaps below it are about 4 mm. long. 

 The arms unite in a point at the apex, and a separate figure 

 giving an apical view shows that there were only four of 

 tliem. 



All the figures agree in making the gaps between the arms 

 shorter than those of my specimens, and rounded instead of 

 pointed below. The three herbarium specimens collected by 

 Thwaites all show the longitudinal striae indicative of the 

 tube-structure of the stalk : each has five arms, the stalks are 

 not perforated, and the gaps below the arms are comparatively 

 long and narrow, as in my specimen. In the last respect they 

 do not agree with the figures. 



Fischer (Engler-Prantl, Pflanzenfamilien) says that Colus 

 Gardner i shows transition to Anthurus : in the arrangement of 

 the ffleba on the iimer face and sides of the arm it resembles 

 Anthurus more than Colus, but it dift'ers from the former in 

 having the arms united at the apex. But although there may 

 be a superficial resemblance to Colus in the dried specimens 

 and figures, great difi^erences are apparent when the head is
